摘要：
The determination of non-dimensional displacement amplitudes and flexural moments for a rectangular plate under a uniformly distributed static load is discussed. The calculations are performed for isotropic, orthotropic and anisotropic plates with uniform thickness and with a single cutout of equal aspect ratio. The Rayleigh-Ritz variational approach is used for the determination of flexural moments and amplitudes. Using the method, the displacement amplitude is expressed in terms of double Fourier series, then deduced the energy of non-existing portion.
